Histamine Receptor
Histamine receptors are GPCRs that mediate the effects of histamine, a biogenic amine involved in immune responses, gastric acid secretion, and neurotransmission. There are four subtypes of histamine receptors (H1, H2, H3, and H4), each playing distinct roles in allergic reactions, gastric function, and central nervous system activity. Histamine receptor antagonists are widely used in the treatment of allergies, peptic ulcers, and motion sickness. At CymitQuimica, we provide a comprehensive selection of high-quality histamine receptor modulators to support your research in immunology, gastroenterology, and neuropharmacology.
